Java ApachePOI:NoClassDefFoundError:org.apache.poi.openxml4j.exceptions.invalidFormatException

当我想要部署我的项目时，我对tomcat有一个问题。构建步骤工作正常，但在部署过程中会出现以下错误：

希望您能帮助我

我的库不在project.xml文件中，因此tomcat无法加载它们，即使项目已编译。。。Tanks for help

此错误通常在库版本不匹配时发生。生成路径！=部署/运行时路径。运行时您有哪些罐子？你错过了哪些？添加时会发生什么？我的库不在project.xml文件中，因此tomcat无法加载它们，即使项目已编译。。。如需帮助，您可以将自己的答案标记为正确答案；-）是的，我等了整整一天才^^很高兴你把它整理好了！
